In defense of my point:
1) the turn of the century (circa 1900s) was a very different time. The population was predominately rural, and approximately 40% of the workforce was involved with family farming. The population today is primarily urban/suburban, and I think the farming numbers today are approximately 3%. Moreover, the costs of entry to many businesses is far higher today than it was 100 years ago. Industry is more complicated; tools and equipment are more expensive. I'm not going to get into a debate about which is better, but it is different.
2) One also might say that a law school graduate would have all of the skills necessary to become a business owner, but I know for a fact that isn't true. There is nothing taught in law school (or for that matter in commercial/CFI training) about business financing, managing employees, managing payroll, marketing, business regulation, or any of the other, varied tasks required to run a business. Law school teaches you how to be a lawyer (sort of); flight training teaches you how to be a commercial pilot/CFI; neither teaches the fundamental skills for business ownership.
3) You are right: today, employees always are at risk of a layoff; there is no promise of a "free ride." But, you can't honestly argue that starting a business carries no more risk than taking a job. The business failure rate is far higher than the layoff rate for employees. Further, an employee does not carry the downside risk of a business failure; whereas an entrepreneur (in most cases) will have put at least some of his/her own money on the line to be lost in the event of failure (the reverse, of course is that the entrepreneur carries upside risk, as well, while the employee generally doesn't). In fact, every great entrepreneurial story I'm aware of includes at least one disaster or near-disaster (Kroc would have been ruined if he hadn't convinced the McDonald's to sell-out; the Kings had a prior business which failed completely). Not everyone is comfortable with or suited to that kind of risk.
4) Most entrepreneurs are (to the rest of us) a little crazy. I meet a lot of entrepreneurs and business owners in my work, and they all are far more comfortable with risk than I would every be (I am the prototypical lawyer: conservative and risk-adverse). Entrepreneurs are comfortable making big decisions involving lots of money and the fate of the business. Those of us who aren't comfortable with risk or with making quick, important decisions probably won't do well in that capacity (see #3).
5) There are some occupations which simply are not suited for entrepreneurialship (is that a word??). For example, if your dream is to fly 747s, you basically have two choices: work for someone else, or become really, really, really wealthy.
In any case, if you do have the stomach for it, setting out on your own and casting off the yoke of an employer taking his/her own cut of your efforts can be very rewarding, financially and mental. But it is a mistake to think that everyone can do it, because not everyone can.
Now, if you want to talk about the masses rising up against their capitalist oppressors, then we'll have some fun. Viva la revolucion!
